"It's horrific. I've never seen anything like it in my life," driver Martin Stammers, 45, told The Telegraph. "All you could hear was the screeching of car tires and the thudding, which was endless. It must have been going on for five to 10 minutes. You could hear the screeching, you could hear the lorries thudding into cars, you could hear glass breaking, there was nothing we could do. Even after the police turned up, you still heard further down the bridge — a quarter of a mile, half a mile away — cars still going into the back of each other."
